The geometry, sedimentary filling and depth estimate of the Mirandiba Basin, Pernambuco, Brazil: new insights about the depositional regional gap of rift phases in the interior basins
Autor: Débora Melo Ferrer de Morais, Roberto Gusmão de Oliveira, Geysson de Almeida Lages, Manoel Júlio da Trindade Gomes Galvão
Publikováno v: Journal of the Geological Survey of Brazil, Vol 4, Iss 1 (2021)
The Mirandiba Basin has a well-defined stratigraphic sequence and its sedimentation may be directly correlated with the Jatobá Basin and some other interior basins. The sedimentation began in intracratonic conditions with a Paleozoic sequence (Tacar

Publikováno v: Brazilian Journal of Geology, Vol 50, Iss 2 (2020)
Abstract One of the main characteristics of the Borborema Province in northeastern Brazil is the abundance of granitic domains. The Lagoa das Pedras plutonic-volcanic Complex record remnants of early to late Neoproterozoic primitive to highly evolved

The Borborema Province in NE Brazil is part of a large Neoproterozoic orogenic system related to the assembly of West Gondwana. Its evolution is contentious, due to the superposition of events that overprinted former records. We present a compilation

Statherian-Calymmian (ca. 1.6 Ga) magmatism in the Alto Moxotó Terrane, Borborema Province, northeast Brazil: Implications for within-plate and coeval collisional tectonics in West Gondwana
Autor: Geysson de Almeida Lages, Elton Luiz Dantas, Joseneusa Brilhante Rodrigues, Lauro Cézar Montefalco de Lira Santos, Roberta Galba Brasilino
Publikováno v: Journal of South American Earth Sciences. 91:116-130
We present geochronological, geochemical, and isotopic data on Statherian–Calymmian metaplutonites located within the Alto Moxoto Terrane (Borborema Province, Brazil). The Carnoio Suite occurs within a large area of this terrane. It is characterize

The Alto Moxoto Terrane of the Borborema Province presents a wide exposure of Paleoproterozoic crust, but unlike other continental blocks of South America, its orogenic history is strongly obliterated by late Neoproterozoic deformation. New isotopic
